-Glorious 1 bit audio.
-CV on all controls.
-Gate output for external ADSR (or whatever).
-Clock or trigger input.
-Arduino-compatible programming header, code provided.
-Unused I/Os broken out for hacking.
All inputs can be CV controlled (0-5V), including the built-in clock-divider. It uses standard 10 pin +12/-12 power, drawing a paltry 30mA.
It’s triggered by sync-24 clock or trigger/gate. It has a handy gate output to easily (and accurately) apply an envelope to each hit whether it’s triggered or clocked (you can see the gate in action in the video below as it triggers the oscilloscope.) Output is 10Vp-p.
